(REUTERS) — Five hikers died on Monday when they were buried by rubble from a rock slide in the Colorado Rockies southwest of Denver but a 13-year-old girl was rescued, an official said.

Mountain rescuers had been dispatched in an attempt to save the five hikers before they were confirmed dead, said Chaffee County spokesman Dave Cotten.

The Chaffee County sheriff’s department was alerted late Monday morning by an emergency 911 call from a woman reporting she had been struck in the head by a falling rock and that several people were trapped in the avalanche, county spokeswoman Monica Broaddus told Reuters.
